This;invention has g to do with awrench andA it is an obj ect oftheinvention toprovide an effective,l improved, quick, adjustable An objectofthisinvention is to providea quick 'adjustable wrench which isextremely simple andl convenient .to operate.-

itively set-when'the-jaws are in operative position. i provide a wrenchofy thevk character described whichyissimpl-e, e'ectiiffey and practicalin construction. Y The objectsandfeatnres ofmypresent invention will .beAbest :and more? fully understood :from the following Vdetaileddescripfy tion-,of a typical form and applicationot the invention,thronghoutwhich "description, rei accompanying drawings Fig. 1 is a'sideelevationofa wrench embodying a. typical g formofthe presentin- Fig.2 isa sectionallviewof the wrench shown'in Fig. 1. j v

Fig.y 3 isan enlarged transverse' sectional .view taken' substantiallyas indicated by line 3,'-3 on Fig.v 1y showing the wrenchfin releasedposition, thatis, in. position to allow foradjustmentfor'thegjaws, and iA Fig. tis aview'similar'to Fig'. 3 showing the wrench set or inposition -or operation.

My present invention is.-in itsabroader sense,` applicable tok wrenchesof lvarious typesand is capable of embodiment in various forms ofconstruction. I have, 'for purpose of'illustration onjly,fchosen to setforth the invention in wrench of the type usuallyemployedfor-handlingpipa and the like, vand have set forth a simpleandtypical form of construction. It Vis to be .distinctly understoodthat the disclosure made in this application is not-to be considered aslimitingf'the scope or rangeof applicationof my inventio.y

The tool illustrated inthe drawings includes, generally, a handle 10, arelatively stationaryjaw 11, anfadjustable Vjaw 12 and variousotherparts.' the details of which will befhereinafterset i'orth.V rl `hehandle `10 is A urther'object of-this invention is-to -moved by thespring, Y

designedsothat itsouter end-portion 13 forms a handle for thetool,jwhile-its inner portioncarries the working parts of the tool.

The handle 10 may, yasfar as the present invention is concerned, bedesigned and yconstructed'in' the manner usual to devices of thisgeneralcharacter. Anotheriobject'ofthis inventlon'is to'lprovidefaquick, adjustable wrench which is pos The vjawll is a stationary-jawconnected or` formed with the `handle 10. In the particular caseillustrated in the drawings, the

- jaw isrigidly mounted on the inner Vend of `the handle 10. Y The jawis formed separate A with lthe handle 10,' so that-it isfadrjnstable itoward and away from the jaw 11.l In the particular type ofwrenchillustrated in the drawings the javv-v 12 is connected with the handle10 by meansof a shank 15 provided on fthe Vjaw 12 and a; carrier l16whi`ch is provided on` the handle 10 .and carries thershan'k. 15. Theshank 15 is preferably formed with the jaw 12cand is substantiallyvparallel with the handle 1 0.k l'l`he`carrie'r'16 provided on.y

vor in connection with, the handle 10 isin substance a part orcontinuation of the handle 10.1 In the particular'construction shown e.in the drawings the ycarrier '16 is-formed separately from the handle.and is connected thereto by a pivot pin 18,- The carrier and handle arerelated so that the carri-er hasa limited pivotal movement withreference to the lever. The'carrierextends longitudinally of the leverand is located-at Vtherear of the handle as Vclearly illustratedin Fig.`1 of the drawings. The pivotal connection between the 'carrier andhandle is at the inner end of the carrier,y A spring 20isar ranged inconnection Awith .the otherl end of the carrier .to normallyvyielvdingly' holdit laway `trom the handle. VProjections v21 on the`carrierl cooperate with stops 22-on the handle to limit thefamountlthe1ca'rrieris .In the preferred 'form of my 'presentin-f vention theshankfl of the jaw 12 is roundV in cross-sectional configuration vand iscarried in a round Opening 24 in the carrier 16.

The shank is carried' in the Opening 24 so that it can be rotated andvalso moved loning being provided with projections, the" jaw, a shank onthe' movable jew 'freely carred in the opening, the Wall 'of saidopenshank being providedwith series of teeth to cooperate with thelprojections of the carrier7 the shank having a recess adjacent theteeth to receive the teeth; of the carrier, and a spring pressed plungermounted 1n ther carriery to` extend into the opening and .19th day ofSept.,' 1924.
